Wisconsin ratification of the 19th Amendment
Wisconsin ratified the 19th Amendment to the Constitution, which granted women the right to vote, on June 10, 1919. This amendment was first introduced into Congress in 1878. On May 21, 1919, the House of Representatives passed the amendment, and two weeks later, the Senate followed. When Tennessee became the 36th state to ratify the amendment on August 18, 1920, the amendment finally obtained the required agreement of three-fourths of the states. Secretary of State Bainbridge Colby certified the ratification on August 26, 1920.
